La transformación del currículo en una sociedad diversa : ¿quién y cómo se decide el currículum?
2018
The purpose of this article is to show how, in the United States, some states and school districts are transforming their curriculum through ethnic studies. Ethnic studies exists as a result of unequal power relations in which historically marginalized groups have not had the power to define how education will serve their own communities. According to its activists, ethnic studies not only teaches about the cultures of diverse groups, but also reconstructs, the curriculum around the counter-narratives perspectives, epistemologies, and visions of groups that have been treated historically as if their experiences and perspectives were of lesser value. The article begins with a theoretical fra…
How Do Students Value the Importance of Twenty-first Century Skills?
2014
Frameworks of twenty-first century skills have attained a central role in school development and curriculum changes all over the world. There is a common understanding of the need for meta-skills such as problem solving, reasoning, collaboration, and self-regulation. This article presents results from a Finnish study, in which 718 school pupils aged 11 to 15 years were asked to anticipate the skills they would need in the future. Accordingly, they were asked to value and rank the twenty-first century skills listed in existing frameworks and pick out those they regarded as the most important they had learned. Social skills and collaboration were ranked highest, both in the listed frameworks …
VALUTAZIONE DELLE PERFORMANCE E ATTIVITÀ DI INDIRIZZO, MONITORAGGIO E CONTROLLO SULLA PROGRAMMAZIONE PUBBLICA REGIONALE DEI FONDI STRUTTURALI. APPROC…
2014
La programmazione pubblica regionale attraversa un momento di forte criticità interna legata al soggetto attuatore regionale, caratterizzata da una lentissima attuazione dei programmi operativi cofinanziati dalla Commissione Europea. In risposta alle emergenze economiche e sociali, l’amministrazione regionale necessita di strumenti in grado di comunicare efficacemente azioni e risultati che possono positivamente influenzare la vita sociale e civile della comunità regionale. In particolare, gli operatori economici e, in generale, tutti i portatori di interesse, basano i propri atteggiamenti e le proprie scelte sulle aspettative delle dinamiche attese nei settori economici e sociali in cui op…
Comparing Traditional and IRT Scoring of Forced-Choice Tests.
2018
This article explores how traditional scores obtained from different forced-choice (FC) formats relate to their true scores and item response theory (IRT) estimates. Three FC formats are considered from a block of items, and respondents are asked to (a) pick the item that describes them most (PICK), (b) choose the two items that describe them the most and the least (MOLE), or (c) rank all the items in the order of their descriptiveness of the respondents (RANK). The multi-unidimensional pairwise-preference (MUPP) model, which is extended to more than two items per block and different FC formats, is applied to obtain the responses to each item block. Traditional and IRT (i.e., expected a po…
Development of a Fractional PI controller in an FPGA environment for a Robust High-Performance PMSM Electrical Drive
2021
This paper proposes the application of a Fractional Order PI (FOPI) in the speed loop of a high performance PMSM drive to obtain both speed tracking and load rejection performance with a 1-DOF Proportional Integral (PI) controller and 2-DOF Integral Proportional (IP) controller. Hardware validation was implemented in Field Programmable Gate Array on the LabVIEW environment, based on the National Instruments System-on-Module sbRIO-9651 with Xilinx Zynq-7020. Simulation and experimental results are presented to comparing the performance of a PI, IP and FOPI controllers in the speed loop of a Field Oriented Control (FOC) of a Permanent Magnet Synchronous Motor (PMSM).
Dual Inequalities for Stabilized Column Generation Revisited
2014
Column generation (CG) models have several advantages over compact formulations: they provide better linear program bounds, may eliminate symmetry, and can hide nonlinearities in their subproblems. However, users also encounter drawbacks in the form of slow convergence, also known as the tailing-off effect, and the oscillation of the dual variables. Among different alternatives for stabilizing the CG process, Ben Amor et al. [Ben Amor H, Desrosiers J, Valério de Carvalho JM (2006) Dual-optimal inequalities for stabilized column generation. Oper. Res. 54(3):454–463] suggest the use of dual-optimal inequalities (DOIs) in the context of cutting stock and bin packing problems. We generalize th…
Skeletons for parallel image processing: an overview of the SKiPPER project
2002
International audience; This paper is a general overview of the SKIPPER project, run at Blaise Pascal University between 1996 and 2002. The main goal of the SKIPPER project was to demonstrate the appli- cability of skeleton-based parallel programming techniques to the fast prototyping of reactive vision applications. This project has produced several versions of a full-fledged integrated pa- rallel programming environment (PPE). These PPEs have been used to implement realistic vi- sion applications, such as road following or vehicle tracking for assisted driving, on embedded parallel platforms embarked on semi-autonomous vehicles. All versions of SKIPPER share a common front-end and reperto…
Systematic classification of two-loop realizations of the Weinberg operator
2015
We systematically analyze the $d=5$ Weinberg operator at 2-loop order. Using a diagrammatic approach, we identify two different interesting categories of neutrino mass models: (i) Genuine 2-loop models for which both, tree-level and 1-loop contributions, are guaranteed to be absent. And (ii) finite 2-loop diagrams, which correspond to the 1-loop generation of some particular vertex appearing in a given 1-loop neutrino mass model, thus being effectively 2-loop. From the large list of all possible 2-loop diagrams, the vast majority are infinite corrections to lower order neutrino mass models and only a moderately small number of diagrams fall into these two interesting classes. Moreover, all …
Run-Time Reconfiguration for Emulating Transient Faults in VLSI Systems
2006
Advances in circuitry integration increase the probability of occurrence of transient faults in VLSI systems. A confident use of these systems requires the study of their behaviour in the presence of such faults. This study can be conducted using model-based fault injection techniques. In that context, field-programmable gate arrays (FPGAs) offer a great promise by enabling those techniques to execute models faster. This paper focuses on how run-time reconfiguration techniques can be used for emulating the occurrence of transient faults in VLSI models. Although the use of FPGAs for that purpose has been restricted so far to the well-known bit-flip fault model, recent studies in fault repres…
Genetic parameters for early lamb survival and growth in Scottish Blackface sheep1
2008
The objectives of this study were 1) to estimate the heritability of lamb survival and growth in the Scottish Blackface breed; 2) to examine the relationship between lamb survival and live BW; and 3) to investigate the possibility of using lamb survival in a breeding program for this breed. The data used for the analyses contained information about survival and live BW at different ages on 4,459 animals. The records were collected from 1988 to 2003 in a Scottish Blackface flock. Live BW was recorded every 4 wk from birth to 24 wk. Survival was defined either by perinatal or postnatal mortality (up to weaning at 12 wk), or as cumulative survival to 1, 4, 8, and 12 wk. The pedigree file compr…
